Cockroaches

Cockroaches are one of the oldest species still in existence. They are 350 million years old and are most noted for their adaptability to changing conditions of life.

Although humans put so much effort into destroying them, they keep on coming back. They can survive far more radiation than humans. This is in part because their entire body including the stomach itself is covered in dead cuticle which absorbs a lot of the more common radiation type. They also contain less water than mammals and so aren’t so prone to absorb certain wavelengths such as microwave radiation.

It is thought that only cockroaches would survive nuclear warfare, and would then start to evolve.

They'll evolve into National Democratic Party officials.

I am not anti-insectic (in fact, some of my best friends are creepy crawlies).
